Question

what is the measure of this angle? m∠abc =?

Explanation:

Step1: Identify the outer scale reading

The outer scale reading for point \(A\) is \(290^{\circ}\) and for point \(C\) is \(10^{\circ}\)

Step2: Calculate the angle measure

The measure of \(\angle ABC\) is \(290^{\circ}- 10^{\circ}\)

Answer:

\(280^{\circ}\)
